I'm surprised noone has mentioned this....but....had you eaten before you smoked? I mean, you can get high with an empty stomach, but if you really get blazed, it hits you hard. One time I hadn't eaten or drank ANYTHING since 4pm the day before, and it was already noon, we planned on bbq so we went to the store and I passed out in the store. That was early on in my smoking carreer...but if i really want to get bombed, i try to at least have something to drink/eat before/during.
